BYACC/J 语法分析器生成工具

BYACC/J 是扩展和兼容自 Berkeley v 1.8 YACC 的Java的语法分析器生成工具。Standard YACC takes a YACC source file, and generates one or more C files from it, which if compiled properly, will produce a LALR-grammar parser. This is useful for expression parsing, interactive command parsing, and file reading. Many megabytes of YACC code have been written over the years.
